A high-power BLDC motor driver for industrial electric vehicles, delivering 20 kW continuous power from a 180 × 130 mm board, in a design the client fully owns.
The challenge
The client builds industrial electric vehicles and runs its own complex motor-control algorithms. An off-the-shelf driver would have left the hardware a black box, so they wanted a design they own completely and can tune and extend themselves.
The driver had to deliver 20 kW continuously and 40 kW peak from a 100 V system, fit a 180 × 130 mm footprint, and protect itself and the vehicle against overvoltage, overcurrent and shoot-through.
What we built
Hardware
A power stage and a separate STM32 control board, stacked into one 180 × 130 mm unit.
Firmware
Firmware that tests every interface on the board and lets the controller be updated over Ethernet or CAN.
Delivery
A tested design and everything needed to build it, refined over two hardware iterations.
